Probability is about estimating or calculating how likely or 'probable' something is to happen. The chance of an event happening can be described in words, for example ‘certain’, ‘impossible ...

An event which is impossible has a probability of 0 and an event which is certain has a probability of 1. This means probabilities cannot be bigger than 1. This can be shown on a probability scale.
